An attacker could exploit this vulnerability by authenticating to an affected device, creating a crafted command string, and writing this crafted string to a specific file location. A successful exploit could allow the attacker to execute arbitrary operating system commands as root on an affected device. The attacker would need to have valid administrator credentials for the device.

A vulnerability in the update service of Cisco Webex Meetings Desktop App and Cisco Webex Productivity Tools for Windows could allow an authenticated, local attacker to execute arbitrary commands as a privileged user. The vulnerability is due to insufficient validation of user-supplied parameters. An attacker could exploit this vulnerability by invoking the update service command with a crafted argument. An exploit could allow the attacker to run arbitrary commands with SYSTEM user privileges. While the CVSS Attack Vector metric denotes the requirement for an attacker to have local access, administrators should be aware that in Active Directory deployments, the vulnerability could be exploited remotely by leveraging the operating system remote management tools. This vulnerability is fixed in Cisco Webex Meetings Desktop App Release 33.6.6 and 33.9.1 releases. This vulnerability is fixed in Cisco Webex Productivity Tools Release 33.0.7.

A vulnerability in the CLI of Cisco Firepower Threat Defense (FTD) Software could allow an authenticated, local attacker to perform a command injection attack.

A successful exploit could allow the attacker to execute commands with root privileges.

A vulnerability in the filesystem permissions of Cisco NX-OS Software could allow an authenticated, local attacker to access sensitive data that could be used to elevate their privileges to administrator. The vulnerability is due to improper implementation of filesystem permissions. An attacker could exploit this vulnerability by logging in to the CLI of an affected device, accessing a specific file, and leveraging this information to authenticate to the NX-API server. A successful exploit could allow an attacker to make configuration changes as administrator. Note: NX-API is disabled by default.

A successful exploit could allow the attacker to establish an interactive session with elevated privileges. The attacker could then use the elevated privileges to further compromise the device or obtain additional configuration data from the device.

A vulnerability in the NX-API feature of Cisco NX-OS Software could allow an authenticated, local attacker to execute arbitrary code as root. The vulnerability is due to incorrect input validation in the NX-API feature. An attacker could exploit this vulnerability by sending a crafted HTTP or HTTPS request to an internal service on an affected device that has the NX-API feature enabled. A successful exploit could allow the attacker to cause a buffer overflow and execute arbitrary code as root. Note: The NX-API feature is disabled by default. MDS 9000 Series Multilayer Switches are affected in versions prior to 8.1(1). Nexus 3000 Series Switches are affected in versions prior to 7.0(3)I4(8) and 7.0(3)I7(1).

A vulnerability in the Bash shell implementation for Cisco NX-OS Software could allow an authenticated, local attacker to escalate their privilege level by executing commands authorized to other user roles. The attacker must authenticate with valid user credentials. The vulnerability is due to the incorrect implementation of a Bash shell command that allows role-based access control (RBAC) to be bypassed. An attacker could exploit this vulnerability by authenticating to the device and entering a crafted command at the Bash prompt. A successful exploit could allow the attacker to escalate their privilege level by executing commands that should be restricted to other roles. For example, a dev-ops user could escalate their privilege level to admin with a successful exploit of this vulnerability.

A vulnerability in the development shell (devshell) authentication for Cisco Aironet Series Access Points (APs) running the Cisco AP-COS operating system could allow an authenticated, local attacker to access the development shell without proper authentication, which allows for root access to the underlying Linux OS. The attacker would need valid device credentials. The vulnerability exists because the software improperly validates user-supplied input at the CLI authentication prompt for development shell access. An attacker could exploit this vulnerability by authenticating to the device and entering crafted input at the CLI. A successful exploit could allow the attacker to access the AP development shell without proper authentication, which allows for root access to the underlying Linux OS.
